Check Digit Verification of cas no

The CAS Registry Mumber 1373139-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,1,3 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1373139-23:
(9*1)+(8*3)+(7*7)+(6*3)+(5*1)+(4*3)+(3*9)+(2*2)+(1*3)=151
151 % 10 = 1
So 1373139-23-1 is a valid CAS Registry Number.

Ti-catalyzed homolytic opening of ozonides: A sustainable C-C bond-forming reaction

Rosales, Antonio,Munoz-Bascon, Juan,Lopez-Sanchez, Cristobal,Alvarez-Corral, Miriam,Munoz-Dorado, Manuel,Rodriguez-Garcia, Ignacio,Oltra, J. Enrique

experimental part, p. 4171 - 4176 (2012/06/18)

The unprecedented homolytic opening of ozonides promoted and catalyzed by titanocene(III) is reported. This novel reaction proceeds at room temperature under neutral, mild conditions compatible with many functional groups and provides carbon radicals suitable to form C-C bonds via both homocoupling and cross-coupling processes. The procedure has been advantageously exploited for the straightforward synthesis of the natural product brittonin A.
